Privacy Policy
Effective April 29, 2026 · Last updated May 4, 2026
Taper is a swim training journal app for iOS. This policy explains what data we collect, how we use it, and your choices. We collect only what we need to run the service. We do not sell your data. We do not run ads.
Information We Collect
When you use Taper we collect:
- Account information — your email address and display name, provided by Sign in with Apple.
- Training profile — pool type, weekly training frequency, and race goals you set during onboarding. This data is stored server-side and synced to your account.
- Workout data — photos of whiteboards you capture, AI-parsed workout sets (distances, reps, rest intervals, stroke types), and total distances.
- Journal entries — optional feel ratings, swim tags, and notes you attach to a workout.
- Subscription status — whether you have an active Taper Pro subscription. Payment details are handled by Apple; we never see your card number.
- Basic device info — iOS version and device model, used only for compatibility and crash reporting.
How We Use Your Information
- Syncing your workouts and profile across your devices via our cloud backend (Supabase).
- Parsing whiteboard photos — images are sent to OpenAI's API to extract your workout. They are not stored by us after parsing and are not used to train OpenAI models.
- Managing your subscription — we share your user ID with RevenueCat to verify your entitlement across devices.
- Authentication — sign-in tokens from Apple are exchanged with Supabase to create your session.
